问题 Building an application using the CEFSharp browser, works fine on my machine, but crashes on the server with the following error: System.IO.FileLoadException: A procedure imported by 'CefSharp.Core.dll' could not be loaded.

问题 I'm trying to iterate the DOM using TChromium and because i use Delphi 2007 i can't use anonymous methods, so i created a class inherited of TCEFDomVisitorOwn.

问题 I'm using CefSharp 1 in my wpf app. How can I download files from sites through my embedded navigator ? When I click on a download link, nothing happens. 回答1: See answer in this thread in the CefSharp group 回答2: You may need to add a shceme handler for the 'file' protocol. That's what we did...
